摘　　要：选择福建三明市陈大国有林场金丝湾森林公园的生态公益林作为研究对象,探讨其树种组成、直径分布、蓄积结构、空间结构等林分结构特征,结合森林可持续经营和结构化经营的思想,对生态公益林林分结构进行优化调整,评价其调整后的效果。结果表明:林分树种组成项数<3,树种较少,林分树种多样性较低;研究区小、中、大径组蓄积比为1.4∶3.2∶5,小径组林木蓄积不足;样地平均角尺度为0.550,属聚集分布,平均混交度为0.505,属中度混交,林分结构不合理。调整后混交度增加,角尺度降低,整体分布格局趋向随机分布,林分空间结构得到良好的改善。Choose the ecological forest of Chenda state-owned forest farm in Jinsiwan Forest Park, Fujian Province to be the object of study. The goal of stand structure optimization and adjustment was extracted by analyzing stand species composition, diameter distribution, volume structure, spatial structure and integrating the concept of sustainable forest management and structured management. The main research showed that tree species and tree species diversity showing a lower state when the coefficient of species composition was less than 3, accumulation ratio of small, medium, and large diameter class was 1.4∶3.2∶5, turn out that small group accumulation was insufficient, forest structure showed not so ideal when the average angle scale was 0.550 and an average mingling degree of 0.505. The predict result showed an increasing of mingling degree and reducing on angle scale after the adjustment, the whole distribution pattern tends to random distribution and stand spatial structure get a large improvement.
